Resolved Question:

I have a Duet washer model GHW9200LW and keep receiving an error code F/H every minute during the wash or rinse cycle. This used to happen occassionaly, but now has progressed to every wash attempt. If I cancel and then continue, it adds more water until it is too full. I had read that it might be the pressure switch hose. I can disconnect the hose from the pressure tube connector at the bottom of the drum and blow in it and hear the switch actuate. Do you think it is the switch itself?

heres what your code means and some possible solutions to try,

No water detected entering machine or Pressure switch trip not detected.

If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.


If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.


Press PAUSE/CANCEL twice to clear the display.
  • If there is no water in the unit:
    1. Make sure that both valves at the water source(s) are turned on all the way.
    2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves
    3. Verify inlet valve operation
  • If there is water in the unit:
    1. Verify Drain pump operation
    2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
  • Verify there is not a siphon problem
  • Verify wire harness connections to:Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU)
  • Check all hoses for possible leaks
  • Verify pressure switch operation
  • Verify flow meter operation
  • Verify CCU operati
let me know if this helps, thanks Bryan

There is water in the unit and it does drain. Pressure switch hose appears to be fine. Wiring harnesses are all in place and no obvious leaks. Did blowing in the pressure hose and hear the switch actuate constitute "verify pressure switch operation? Haven't verified flow meter or CCU, would running the diagnostic test help to determine problem?

Ran diagnostic test and on C:01 & C:03 get the F/H code. All other tests ran properly

I will see what else I can find out in a little while, need to go about for an hour or so. thanks,Bryan

ok you need to check the screens in the hoses and make sure they are both clear, just because theres water in the machine doesnt mean its getting the right flow its probably not getting the right g.p.m. and the machine senses that and sends the code. if its taking to long to fill it will trip the code F/H. let me know thanks,Bryan
